That has the quirks of the taller version (1.5") of the 1960s trademark stamp.

Bill Hartrick (Drumaholic) who originally documented it said it was "later 1960s" vs "early 60s" for the shorter version. I don't know how many examples of short vs tall 60s tademarked cymbals he had accurate dates for. I haven't been able to replicate his claim by correlating lathing or hammering differences between cymbals with the taller or shorter 60s stamp. We don't have accurate years for first use in factory and last use in factory for either version of the 60s stamp. So for now I just talk about 60s.
